Re: My opinions.... (archive)

>>> Yes, its behind this plastic housing. I would replace the housing at the same time because they are known to leak very slowly. The housing costs about $32 Cdn ($21 US).

2. Radiator looks OK with no leak. However, for this car I have heard plastic tank can split causing significant coolant loss quickly.
Should I replace the radiator (which is 6 years old) on a preventive principles?

>>> Difficult to say. I wouldn't because it's an expensive part. Others would because they don't want to be stranded, and pay more later.

3. Type of Antifreeze. It does not seem that this car uses the permanent "red color" coolant. I have been using Prestone on my other Bimmer (E23 1983 735i) with no problems.
Is Prestone OK here?

>>> Prestone is okay. I'm using it.

4. The Water Pump seems fine but I have heard stories about the plastic impeller breaking off with over heat problems. Is this model fit a Water Pump with plastic impeller?
If so, then is this a good time to change to a better OEM water Pump?

>>> DEFINITELY CHECK THE PUMP. The '94 325's had plastic impellers from the factory. It is possible that yours has already been replaced, but you cannot tell without removing the pump. The dealer sells re-built pumps with the new steel impeller for about $90 Cdn ($60 US) plus core charge.

5. Finally the Radiator Hoses seem fine with no cracks when squeezed. Do you guys replace 6-year old hoses or go longer until you see cracks on the hoses?

>>> I don't replace hoses if they still feel soft and smooth like new hoses. If they feel stiff, replace.

>>> Hope this helps.
